Answer:
y = -1
Step-by-step explanation:
Notice that the line x = 9 is a vertical line, therefore a line perpendicular to it will be a horizontal line of the form y = constant number.
Since we want it to go through the point (9, -1), then we know that that y value needs to be "-1", and the equation of the line will be given by the expression:
y = -1

<em>11 2/5 mm³</em>
- Step-by-step explanation:
<em>Hi there ! </em>
<em />
<em>3 4/5mm³ = (3×5 + 4)/5 = (15 + 4)/5 = 19/5 mm³</em>
<em />
<em>19/5 mm³ ............. 1/3 box</em>
<em>x mm³ .......................1 box</em>
<em>x = 19/5×1 : 1/3</em>
<em>= 19/5 × 3/1</em>
<em>= 19×3/5</em>
<em>= 57/5</em>
<em>= 11 2/5 mm³</em>
<em />
<em>Good luck !</em>
